How to use a VPN on Windows is not simply a matter of installing a client. You need to complete the full workflow: obtain a trusted installer, import a valid subscription, choose a route, enable the right proxy mode, and use a network check to confirm that traffic is passing through the selected exit. If any step is incomplete, you may see the client report “connected” while the browser still cannot open websites, or find that websites work while other apps remain unchanged.
This guide follows the practical order for a first-time setup. Interface names vary slightly between client versions, but the troubleshooting logic is largely the same. When a button is named differently, look for entries with similar meanings, such as “Subscriptions,” “Configuration,” “Nodes,” “System Proxy,” “Rule Mode,” and “Startup Settings,” rather than matching every word literally.
What to prepare before you begin
Before installing, confirm the client type and subscription format provided by the service. A subscription may include protocol nodes such as Shadowsocks, VMess, Trojan, VLESS, Hysteria2, or TUIC. Protocol names describe how the client connects to the server; they do not indicate route quality. Suitability for your network also depends on client support, matching server configuration, and how well the local network handles the transport method.
- ✅ You have a Windows-compatible client installer or portable archive.
- ✅ You have copied the complete subscription link, with no extra spaces or line breaks.
- ✅ You have confirmed that the client supports the protocols used in the subscription.
- ✅ You have closed older proxy tools to prevent multiple programs from changing the system proxy at once.
- ✅ You have saved any downloads or remote work in progress so you can identify the impact of a network switch.
An installed client usually creates a Start menu entry and works more easily with startup settings. A portable version runs after extraction and suits users who prefer to manage the program directory themselves. The two versions may offer the same connection capabilities; the main point to watch is where configuration files are stored. With a portable version, do not place it directly in a temporary download folder or move the entire folder while it is running, or shortcuts and local configuration paths may stop working.
Install the Windows client
An installed client usually guides you through setup. When asked for an installation location, the default folder is fine. If you see options for creating shortcuts or starting with Windows, create only the shortcut for now and enable auto-start after the connection has been verified. This prevents an incorrect initial configuration from taking over the network every time you reach the desktop.
- Exit other proxy clients that are running, and check the taskbar notification area for icons from older programs.
- Open the installer. If Windows asks you to confirm the source, verify the file name and publisher before continuing.
- Finish the installation and launch the client. On the first run, Windows Firewall may ask whether to allow network communications; choose according to your network environment and the client’s instructions.
- Once the main interface opens, first find the settings page and confirm the language, configuration directory, and update entry before importing a subscription.
- For a portable version, extract all files first, then launch the program from the extracted folder. Do not run it directly from the archive preview window.
Some clients do not show a regular window after launch and instead minimize to the taskbar notification area. Click the corresponding icon in the lower-right corner to reopen the main interface. If the icon is not visible, use Task Manager to check whether the program is already running. Double-clicking the installer again will not restore a hidden main window and may start multiple processes instead.
Import the subscription link and update routes
Subscriptions are usually imported in one of two ways: from the clipboard or by creating a subscription on the subscription management page. The first is faster; the second makes it easier to review the link and configure automatic updates. Either way, paste the complete address—not the service dashboard URL, a plan name, or an individual node note.
- Copy the subscription link from the service dashboard. Do not manually select only part of the address.
- Open the client’s subscription management, configuration management, or configuration file section.
- Choose Add Subscription, enter a recognizable name, and paste the link into the address field.
- Save it, then choose Update Subscription, Refresh Configuration, or Download Configuration.
- Wait for the route list to appear, then check for protocol names, region names, or route labels.
If the list is still empty after saving, do not keep clicking Connect. An empty list usually means the client has not successfully read the configuration. Common causes include an incomplete link, an expired subscription, an unsupported format, or temporary local network access issues. The right order is to copy the link again, update it manually, and then review the client log for subscription download messages.
“Update Subscription” and “Test Route” are different operations. Updating obtains the latest configuration; testing checks connectivity or latency for nodes that already exist. If the update has not succeeded, the test button cannot create routes. When the service changes its routes, synchronize them with an update instead of repeatedly deleting and reinstalling the client.
Choose a route and traffic rules
The region, protocol, and route type in a route list address different concerns. The region affects the exit location; the protocol determines how the connection is implemented; IEPL dedicated routes, relay routes, and direct routes describe the network path. IEPL dedicated routes generally use specially planned cross-network links. Relay routes connect to an intermediate entry point before reaching the exit, while direct routes connect from the local network to the remote server. Names cannot replace real-world testing, so compare stability on your own network.
| Item | Purpose | How to evaluate it | Common misconception |
|---|---|---|---|
| Exit region | Determines the network exit location visible to websites | Choose based on the target service’s region and your access needs | Looking only at the region name without checking the actual exit |
| Connection protocol | Determines how the client and server transmit data | Prefer a protocol fully supported by the client and stable in testing | Treating the protocol name as a speed ranking |
| IEPL dedicated route | Uses a specially planned international link | Observe stability during peak hours and on long-lived connections | Assuming a route label guarantees the same performance on every local network |
| Relay route | Connects to an intermediate entry point before reaching the target exit | Compare packet loss, connection setup, and sustained transfer performance | Making a decision based only on node test figures |
| Direct route | Connects directly from the local network to the remote server | Worth trying when the path from the local network to the target region is smooth | Assuming a shorter path is always faster in practice |
After choosing a route, you also need to select a proxy mode. Rule mode sends only traffic matching the rules through the proxy, while commonly used local websites and LAN resources can remain on their normal path. Global mode attempts to send more application traffic through the current node and is useful for temporarily checking whether a program was missed by the rules. Direct mode is generally used to pause proxying while keeping the client running.
Beginners can start with rule mode. If the browser works but a desktop program cannot connect, temporarily switch to global mode for comparison. If the program works in global mode, the issue is more likely in the traffic rules than in the node itself. After confirming this, add domain or process rules instead of relying on global mode permanently. Office intranets, printers, and LAN shares should also remain covered by direct rules so local resources are not mistakenly sent to a remote exit.
Some clients also provide TUN mode. The system proxy mainly affects programs that follow Windows proxy settings; TUN mode uses a virtual network interface to handle a wider range of traffic and is more effective for apps that ignore the system proxy. However, it is also more likely to conflict with security software, virtual machines, and other network-filtering tools. For a first setup, verify the system proxy first and enable TUN only if an app is genuinely being missed; troubleshooting will be clearer that way.
Confirm it works with a network check
A client showing “Connected” only means the local program believes the connection is established. It does not by itself prove that the browser, desktop apps, and DNS queries are working as expected. After connecting, open the network check page, compare the exit information before and after, and review the DNS and proxy status.
- Open the check page before connecting and note the currently displayed region and network exit.
- Return to the client, select a route, and enable the system proxy.
- Reload the check page and confirm that the exit has changed to the region associated with the selected route.
- Check whether the DNS results show a local resolution path that is clearly unrelated to the current exit.
- Test both the browser and the desktop program you actually plan to use; do not verify only one website.
A DNS leak occurs when domain-resolution requests are handled outside the expected path and may still be completed by the local network’s resolver. This is not the same as whether a website opens. If results look abnormal, review the client’s DNS mode, rules, and TUN settings, and avoid letting multiple network tools rewrite DNS at the same time. After making changes, close the old connection, reconnect, and test again.
If the exit has not changed, first confirm that the system proxy switch is actually enabled, then check whether the browser has its own proxy setting or extension. If only one app fails, it may not follow the system proxy. If every app fails, the issue is more likely the node connection, a port conflict, or client permissions. Separating these cases is more effective than changing many nodes at once.
Set up auto-start and automatic connection
Configure auto-start only after the connection, traffic rules, and test results are working normally. Common client options include “Start with Windows,” “Start Minimized,” “Update Subscription at Startup,” “Restore Last Node,” “Auto-Connect,” and “Automatically Set System Proxy.” These switches serve different purposes; do not enable every option simply because it says “automatic.”
A safer order is to enable Start with Windows and Start Minimized first, then sign in to Windows again and confirm that the client runs normally. Next enable Restore Last Node. Finally, decide whether to enable Auto-Connect and take over the system proxy. If startup fails, you can then identify the setting responsible instead of losing normal network access immediately after reaching the desktop.
- ✅ The client can be found in the taskbar notification area after startup.
- ✅ The previous subscription and route are still available.
- ✅ If automatic connection fails, you can switch manually to direct mode.
- ✅ After the system proxy is disabled, the local network can access the internet normally again.
- ✅ A failed subscription update does not delete the currently usable local configuration.
If the client offers “Update Subscription at Startup,” remember that the network may not be fully ready as soon as the desktop appears. A failed update does not necessarily mean the subscription has expired; you can refresh it manually later. On computers that frequently change networks, automatic connection may start before public-network authentication is complete. In that case, pause the proxy, finish network sign-in, and reconnect for easier diagnosis.
Troubleshoot common problems in this order
Subscription update fails
Copy the subscription link again from the dashboard and check that it contains no extra characters. Then verify that the system clock is correct, since some secure connections depend on accurate time. Next pause other proxy tools and try again. If the client log says the format cannot be recognized, confirm that the client supports the protocols in the subscription instead of repeatedly refreshing it.
The route test works, but websites will not open
First check that the system proxy is enabled, then temporarily switch from rule mode to global mode for comparison. If global mode works, focus on traffic rules and DNS. If it still fails, switch to another route and reconnect, and confirm that the firewall is not blocking client communications. Do not change the node, protocol, DNS, and mode at the same time, or you will not know which change made a difference.
The browser works, but games or office software does not
This usually means the browser follows the system proxy while the target program does not read that setting. Check whether the client supports per-process routing or TUN mode, then see whether the target program has its own proxy settings. For office intranets, keep internal domains and LAN addresses on direct routing to avoid affecting authentication, shared folders, or internal services.
The internet stops working after exiting the client
The program may not have restored the system proxy before exiting. Open the client again, switch to direct mode or disable the system proxy, and then exit normally. You can also open Windows proxy settings to check whether the manual proxy is still enabled. Once resolved, enable the corresponding client option that clears proxy settings on exit.
A simplified daily workflow
After the initial setup, you do not need to reinstall the client or import the subscription again. Open the client, update the subscription, choose a route for the current task, enable rule mode, and confirm the exit with a network check. If a route becomes unstable, first try another node in the same region. If a protocol fails to connect, compare it with another protocol supported by the client.
A subscription link is access configuration and should be protected like a password. Do not post it in public chats, screenshots, or forums. To use it on another Windows computer, copy it again from the service dashboard and import it into a trusted client. Before deleting the client, if you want to remove local settings completely, disable the system proxy, exit the program, and then handle the configuration directory according to the client’s instructions.
